Calculate the kinetic energy that the earth has because of its rotation about its own axis. For comparison, the total energy used in the US in one year is about 9.33 x 10^9 J

b) Calculate the kinetic energy that the earth has because its motion around the sun.

thank you.

- physics - please help -
